Did you know that there are different classes of fire? Not all fires are created equal, so it wouldn’t make sense for all extinguishers to be created equal either.
Multipurpose Dry Chemical
The extinguisher in your home is most likely a multipurpose fire extinguisher. These contain monoammonium phosphate, a chemical compound that smothers the flames. Since these lack an effective cooling agent, it is important to aim the discharge at the base of the fire as thoroughly as possible to prevent reignition.
Wet chemical extinguishers use a potassium water solution. They have a cooling effect, lowering the temperature of the fire. A variant is commonly used in kitchens, offering better protection against reflash.
Water extinguishers can use pure water, but often have additives like antifreeze and wetting agents to make them more effective and dependable. These units are ideally suited for all industrial and commercial applications, where easy to use, positive on-off operation is important. Pressurized water extinguishers are highly effective on deep seated Class A fires.
Film-forming foam fire extinguishers are most useful against deep-seated fires. These leave behind a blanket of foam which cools and smothers a fire. Foam agents have the opportunity to get to the seat of the fire and prevents reignition.
Clean agent fire extinguishers are a good option when dealing with sensitive electronic equipment. These extinguishers are non-corrosive, nonconductive, and the agent quickly evaporates, leaving no residue. They can be used at a greater distance than other types of fire extinguishers.
Carbon dioxide fire extinguishers are useful for fires that occur in areas with live electrical equipment. The agent discharges as a gas and leaves no residue while depriving the fire of oxygen. It has a short range and is not suitable for windy areas or small spaces, due to life safety concerns.
